Linux has inherited from UNIX the concept of ownerships and permissions for files. This is basically because it was conceived as a networked system where different people would be using a variety of programs, files, etc. Obviously, there's a need to keep things organized and secure.

We don't want an ordinary user using a program that could potentially trash the whole system. There are security and privacy issues here as well. Let's face it, we don't want Bill to read Bob's love letters to the Janet who works in R & D. (because Janet is Bill's fiance) In the end, it's important to know what belongs to me, to you and to everybody.
